CONVEYING AND COOLING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 719,524, dated February 3, 1903.

. Application filed June 8,1901.

To @ZZ whom, t may concern.:

Be it known that I, KARL F. SNOW, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Im provement in Conveying and Cooling Apparatus, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to devices for conveying and cooling hot material, such as the clinker produced in the manufacture of Portland cementas it comes from the kilns used in such manufacture, its object being to effect such coolingin a rapid, eliicacious, and hence economical manner.

Saidinvention consists of meanshereinafter fully described and specifically pointed out in the claims.

The annexed drawings andthe following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting but one of various fthe invention may be used.

In said annexed drawings, Figure I represents a broken side elevation of a structure embodying my invention, illustrating the positions of certain parts connected therewith in outline. Fig. II represents a broken plan view of the structure illustrated in Fig. I. Fig. III represents a horizontal section of one end of a conveyer embodying my invention, showing the interior structure in elevation therein. Fig. IV represents a vertical longitudinal section of a part of such conveyer, showing parts in elevation therein, such section being made on an enlarged scale. Fig. V represents a transverse section of said conveyer, taken upon the plane indicated by line 5 5, Fig. IV; and Figs. VI, VII, and VIII represent detail views ot' parts used in such conveyer. Fig. IX represents a transverse vertical section taken upon the plane indicated by the line 9 9, Fig. III, showing portions in elevation therein. Fig. X represents a detail plan view, and Fig. XI a bottom plan 5o view, of a portion of the means forimparting mechanical forms in which the principle ofl Serial No. 63,689. (No model.)

movement of the material to be cooled through said conveyer, illustrating a series of groups inclined blades utilized for such purpose.

The structure illustrated in the drawings embodies the invention as particularly applied'in the manufacture of Portland cement, and I shall hereinafter describe such invention as so applied. Below the series of rotary kilns A is arranged parallel therewith a series of hoppers b, one beneath each kiln. 6o These hoppers are placed upon and communicate with the interior of a conveying-channel lformed by a top wallb', double side Walls b2, and a double bottom b3, as shown in Fig. V. These walls curve at one end of the conveyerchannel and double back, as shown in Figs.

II and III, the inner shells of the double side walls, as illustrated in this particular instance, ending in both branches of the channel before curving, as shown in Figs. III and 7o IX, such construction being merely the result of economy of construction and not of operative necessity. The inner shell above mentioned falls short of the top wall b', forming thereby a ledge b4, which is utilized for a track, as will hereinafter appear. From the points where said inner shell ends a shell b5, Fig. IX, is secured to the outer shell of the outer side wall, forming a continuation of the outer member of said track. A similar 8o sheli:l b'forming an outside track member,

is provided at the opposite end of the structure, as shown in Fig. X.

The opening formed between the inner and outer shells of the side and bottom walls ends at the points c and c', respectively, as shown in Fig. II, and connected with said ends, respectively, are a water-inlet c2 and a wateroutle't c3, by means of which a stream of water may be caused to continuously iow around 9o in said space between such shells from one end to the other', as will be readily understood.

The conveying-channel ends ci and c5 are left open to communication with the atmosphere, and connected with the curved end is an air-blower D, by means of which a current of air may be caused to continuously flow from one extremity of the structure to the other through both branches of the chan- :oo

nel, such current passing in the construction illustrated in the same direction through both branches simultaneously.

In each end of the structure and at the junction of the ends of the branches of the conveying-channel is located a horizontallyplaced sproeket-wheelE and E', around which passes a sprocket-chain E2, each link of which is composed of a bar E3, formed at one end with a yoke e for receiving the sprocketteeth and a bearing e' at the opposite end, resting in the end of the yoke of the contiguous link and vertically journaled therein bymeans of a journal-pin e2. Each link is suspended from a truck F, provided with two wheels, one mounted at each end of the truckaXle, running upon the track formed by the side walls and shelves. From the middle of each axle is suspended a hanger G, upon the `lower end of which is secured a carrier-bar g,

located transversely of the conveying-channel, as shown in Fig. V. Secured so as to depend from said bar is a series of blades g', capable of angular adjustment relatively to their direction of movement as imparted by the chain E2, as will appear from the following-described construction.

Each blade is formed with a toothed surface g2, Figs. VI, VII, and VIII, which is secured to acorresponding surface formed upon or secured to the bar g. These two surfaces are secured to each other by means of a bolt g3, formed upon the blade and passing into the bar g, and a nut g4, screwed down upon said bar, thus fixing the angular position of each blade.

The blades comprising a group on a bar are caused to be parallel with each other and are given a position of angularity relatively to their direction of travel, the angularity being the same in a series of groups and then changing in the succeeding series of groups to the opposite direction, as shown in Fig. XI. The front surfaces of these blades form groups of conveying planes and extend downwardly into the channel to within a short distance of the bottom thereof, as shown in Fig. V.

Suitable gearing H, Fig. IX, is provided for driving the sprocket-wheels and imparting movement of the conveyer planes through the conveying-channel.

In operation of the above-described apparatus movement is imparted simultaneously with the passage of a continuous current of air through the channel and a stream of water through the water-channel, as provided and described, at bottom and sides of said conveying-channel. The hotfclinker being fed into the hoppers on one branch of the conveyingchannel falls into the latter and is picked up by the blades and carried along as a result of their movement. Owing to the inclination of such blades, however, the forward movement of the clinker is of less speed than that of the side of the channel during its contact with one series of blade groups, having the same direction of inclination, and subsequently toward the opposite side as a result of its contact with those blades having the opposite inclination. The clinkers path of movement is hence sinuous and of a length greater than that of the channel or that part thereof which it traverses. As a result of such increased length of path the clinker passes over an increased amount ofthe cooling-surface afforded by the bottom of the channel and water beneath same as compared with the amount traversed by clinker were the latter to move through the channel by the shortest paththatis,parallel with its sides. Suchincrease of effective cooling-surface, combined with the action of the air-current and increased length of time that the clinker occupies the coolingchannel relatively to the time of occupancy of a con veying-blade, effectsa comparatively rapid and hence economical cooling operation. The cooled clinker is discharged at the open end of the channel,from whence it is conveyed in any suitable manner.

I have found it unnecessary to provide a support for the inner wheels of the trucks when passing around the curves at the ends of the apparatus. In traversing one of these curves the outer truck-wheels run upon the shelf b5, and the truck is supported at its middle by the chain, which in turn is supported by the sprocket tooth, which engages the yoke e of the chain-link in which such truck is journaled, as will be understood from an inspection of Fig. IV. The truck being thus f suspended upon the chain and the latter being secured upon the sprocket-wheel, said truck is carried around the curve while being supported, as described.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any one of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my inventionl. In a conveying and cooling apparatus, the combination of a conveying-channel surrounded by a water-channel, an endless chain operating in such conveying-channel, a series of conveyer devices secured to said chain, means for passing a current of air through said conveying-channel, and means for passing a current of water through said water-channel.
